We have agreed to get a black lab puppy when I will have more time than I have now as I know they are high energy dogs needing lots of mental and physical stimulation. We currently have a cat and a 5 year old Lhasa also and there's just hubby me and our 17 year old daughter. I work three days a week. Don't want to leave it on its own thinking of that borrow my doggie thing springing up. Also work weekends and nights and so wouldn't be left. What can I expect from a lab.
